### 4/5 — One Suggestion

*2025-10-18*

I love everything about this app so far. I am a heavy users of GoodNotes and MarginNotes. I use both of the apps for note taking and study. What I like about this note taking app is it’s user-friendly, it has a white board for mind mapping, and flashcard for studying. I did not get to test white board and flashcard to study yet but this app is very promising. 

One suggestion I have for the developer is if you could allow Apple Pencil to be able to transition from one tool to the previous tool used. The current default setting is it switch between pen and eraser. But for me I rarely use the eraser because you can undo with two taps. I switch my pen a lot more from black and red so it would be huge if you can do that here.

Thank you for the amazing work! and thank you for taking the time to hear my feedback!

### 4/5 — iCloud Sync glitchy

*2025-01-29*

I really enjoyed this app but the cloud sync function seems to be glitchy often. Some of my files are not synced between my two iPads even though both are showing synced to the cloud and some of my notes would get erased if I switch my device. Other than this, great app.

**Developer response:** Hello, the iCloud synchronization problem team will continue to optimize, please keep up to date.

### 4/5 — 请尽快适配apple pencil pro轻捏手势！

*2024-12-07*

轻捏切换橡皮擦真的很需要，特别是带了笔套的pencil

**Developer response:** 您好，Apple Pencil Pro轻捏适配已加入后续开发。

### 3/5 — Squeeze of the Apple Pencil pro is not supported 笔的按压功能无法使用

*2024-09-23*

Squeeze of the Apple Pencil pro is not supported 按压功能无法使用

**Developer response:** Hi，
GUGA has not adapted to Apple Pencil Pro for the time being. 
Sorry for the inconvenience.

The follow-up team will gradually adapt, please keep it updated.🙇‍♂️

### 4/5 — PDH閱覽

*2024-08-30, version 2.0.6*

去年開始使用GUGA，一直很喜歡PHD可以直接以卡片形式閱覽，點開可以變成分割螢幕的形式進行摘錄，但今年改版2.0後，這兩個功能都改變了TT，尤其卡片形式的PDF不僅不能閱覽，點開也會先變成一個小視窗，超級小，也無法以分割螢幕的方式閱覽了，請問之後有機會讓這兩個功能回歸嗎？

### 2/5 — 升级以后我pdf上笔记全丢了

*2024-08-22, version 2.0.1*

自动升级以后我在导入的PDF上做的手写笔记全丢了。那是我半个学期的全部心血。不敢用了

### 3/5 — Potential to be huge

*2024-03-11*

The devs are just not responsive to English customers.

**Developer response:** Hello!
Glad to hear from you.
The GUGA-Hyperboard team is committed to providing a high-quality experience to customers around the world, 
and listens to feedback and suggestions from users around the world.

### 2/5 — 好多bug

*2023-10-15, version 1.0.10*

我好像你们的bug测试员我凭一己之力试了一大堆bug，想知道反馈入口在哪里 以及，双指画圈撤回真的很鸡肋因为一般画错写错只想撤销一步或者两部，画圈真的很难控制很容易失误操控，多撤销了好多步的情况时常发生。以及如果在把一条直线从图片外画到图片内就会自动在两端加上点且无法撤销真的很难受，而且无法用橡皮擦掉图片上的剪号和这种有端点的标注线， 只能一条一条选中删，我只是想单纯画一条直线啊！在画曲线的的时候画完就无法编辑曲率，在作图写笔记的时候带来了不少麻烦。 能不能加一个调节笔大小的时候可以输入数字来调节，想要保持每个笔触大小一样要操作很久。

### 2/5 — 很好的aqq

*2023-10-06, version 1.0.10*

一直使用了一年左右，但是最近在使用时发现有些卡顿，尤其是使用尺子的时候，写字会有明显的延迟，而且在粘贴图片的时候也会，可能是一篇里面图片较多的原因，还是希望能修复下，之前给打了五星，但是最近一直在用，发现卡顿越来越明显，尤其是写字的时候，笔和平板都没有问题，是什么情况？还有最近总是写着写着就没了，有的时候要找好久才会出现，点那个小圆圈也没有用

### 5/5 — 很好的aqq

### 5/5 — whiteboard viewing feature

*2023-09-13*

看三月份 的评论说是 有 手机 或者 电脑 可以看 guga 文件的 feature 现在 有出来了吗 软件很好用 但 想从电脑又 打开不了 guga 文件 截图 或者 pdf 也是 糊 希望 能有解决方案

**Developer response:** 您好，感谢您的反馈。

GUGA团队已经在开发iPhone及Mac版本了，敬请期待！
关于导出PDF/Png格式出现模糊问题，
可能与导出时所选范围大小有关。
请至App主页右下角社区“错误&问题”板块与我们联系。
🙇‍♂️

### 5/5 — 越来越好，未来可期

*2023-09-08*

陆陆续续用了一个月了吧，感觉还是很棒的。但是有些操作逻辑不符合移动端的习惯，更像电脑的逻辑。

**Developer response:** 您好，感谢您对软件的认可。
您提到部分操作尚待优化，
方便到App主页右下角社区愿望&建议板块，
具体列举一下希望优化的部分吗。
非常期待收到您的建议。
Have fun with GUGA🤘

### 1/5 — I can't accept your Terms

*2026-01-08*

I use iPhone 15 Pro. When I open this app first, I can't check Terms and Privacy Policy. please fix it.

### 1/5 — 无法登入

*2025-10-30*

无法登入

### 1/5 — 所有笔记都消失了

*2024-12-14, version 2.0.30*

本来因为喜欢笔触和无限画布买了永久会员，还写了有很多白板，都是很珍贵的笔记，icloud备份啥的都开着，上半年用过，因为我两个设备都开着，本地都存了笔记的，以前一直用没啥问题。然后有半年不用了，今天想起来看看我的笔记，点开第一眼还晃了一下以前的笔记们，然后就闪进重新登陆界面，登陆之后发现：1. 我成免费会员了 也不知道上哪找回我的购买，也没找到反馈或者售后按键 2. 笔记全部清空了，一片空白等着你。。。绝望，愤怒，不解，有什么解决方案吗？

### 1/5 — 使用双指撤回功能时频繁出现闪退

*2024-03-17*

分屏上课记录时，使用双指撤回功能，闪退严重

**Developer response:** 您好，非常抱歉出现闪退故障。
请通过App主页右下角GUGA官方社区向管理员反馈您的情况，
点击管理员头像可以上传视频。
我们会根据您反馈的使用场景，进行故障排查。
尽力修复问题。🙇‍♂️

### 1/5 — 可能是因为给了其他带路党过多费用，研发没跟上＿经历了丢资料等困恼．整体而言只能作为能用但不能成为唯一好用

*2023-09-20, version 1.0.9*

可能是因为给了其他带路党过多费用，研发没跟上＿经历了丢资料等困恼．整体而言只能作为能用但不能成为唯一好用

### 1/5 — 如果不是最低一星我连一星都不想给

*2023-08-24*

你们软件能不能在使用前就标准好免费试用次数还有多少 弄了一半告诉我要收费 早干嘛去了 垃圾。

**Developer response:** 您好！点击主界面左上方的icon，您可以看见实时的剩余白板和卡片剩余数量。

### 1/5 — Can’t login

*2023-03-17, version 0.9.46*

My Apple doesn’t let me log in so I can’t even login in 

You should allow sign in with Google

### 1/5 — Export features is worthless

*2023-02-14, version 0.9.45*

I love the its best i wanted to give 5 star, but to draw makers attention which i am hopeful he will listen to me, i am giving 1 star, once this draw back is solved i will change my rating.

Export feature ask for snapping of particular area which could be good as a additional feature but what user need is exporting whole canvas as pdf without any limitation .

Also exported pdf is not vector based specifically brush strokes , text , line drawn , shape objects , connections,
Basically we need all things to be vector based excepts raster images added which understandable , 

And developers should know this 2 features are already supported by other  similar applications  .

I am hoping you will resolve it i had used community tab but reply was not good there. Thank for this beautiful app. Love you developers 😍

**Developer response:** Hi there～
Whether it's 1 or 5 stars, we still thank you for your message. For the questions you mentioned, we are thinking about how to optimise. However, the export of whiteboard content is directly related to the performance of the device. Large-area and high-definition image export does face many difficulties. Please pay attention to our every progress!   Still Love You❤️

### 1/5 — 价格相差好大

*2023-01-16, version 0.9.44*

美区价格14.99USD，中国区30RMB？差这么多？

### 2/5 — 无法转换成闪卡

*2024-09-13*

不知道是不是苹果中国商城和美国商城是不同的版本。我无法转换闪卡，也无法用脑图。

**Developer response:** 您好，各区域上架的都是相同的版本，我们希望能够与您取得进一步沟通。
请在App主页面左侧边栏找到GUGA社区，点击社区置顶贴，点击管理员头像，发送您的录屏给管理员，我们会根据您的操作排查无法成功转换闪卡的原因，以及无法正常使用脑图功能的原因。

GUGA 2.0.13版本已发布，可以到App Store更新。

### 5/5 — 有一点小问题

*2026-03-07, version 2.0.38*

荧光笔的方向不会随着pencil的转动而转动，并且每次方向是随机的，想要调方向就要转动笔的朝向，不太好用。

### 5/5 — Perfect for me

*2025-07-01, version 2.0.31*

So happy to have found this. It just works exactly how my brain does. Love the weight of the pen stokes, the simplisity, the nesting of notes. Really well designed and considered app - Perfect for me and rare not have a subscription model. Love it ❤️

### 5/5 — 喜欢

*2025-02-23, version 2.0.31*

好用，不会拖慢iPad的速度

### 5/5 — 👍👍👍

*2024-12-19*

### 5/5 — Love it!

*2024-12-16*

I initially faced some issues using it, but the developers quickly responded to my request, and now it works perfectly. This app makes studying more efficient and enjoyable. 
Thank you, GUGA team, for creating such a brilliant app and special thanks to KAN ER YE for recommending it to me!

### 5/5 — Perfect

*2024-10-23, version 2.0.21*

Exactly what I need. Please make for mac os with iCloud syncing!

### 5/5 — Absolutely beautiful app

*2024-10-03, version 2.0.16*

I can search my handwriting! I use GUGA for my studies, my clinical practice, my research projects, and my creative journaling, it is a complete game changer and I don’t think can go back to GoodNotes or Notabilty.

### 5/5 — Great App Design !

*2024-06-29, version 1.0.15*

Very good intuitive and attractive interface with built-in help for every feature. The first board I made was a mindmap of all the app features, using the help menu to easily identify each one. It’s got all the usual mindmap tools plus lasso, calculator/conversion tool, topic frame, lazer pointer and quick import for links, pins, images and files. 

Two stand-out features, for studying, are being able to make a library of custom built images/diagrams/documents (cards) and a pdf reader that expands from a thumbnail to a full file reader that can be viewed in split screen. 

A few of the advanced features, in help, are still in Chinese but the diagrams and videos can still be followed. Other than that excellent !

### 5/5 — Overall is good

*2024-06-07, version 1.0.15*

But there is a bug, when you try to use lasso tool to move object, it always stuck when first try, it will stuck in the middle when you drag

Also, please add auto backup to other cloud drive, too. Like, google drive, one drive to increase the stability and prevent data loss

### 5/5 — 好好好

*2024-02-22*

非常棒🎉

**Developer response:** 您好，非常感谢您对团队及产品的认可与支持！

团队会继续努力💪

后续还会有功能更新，敬请期待。

Have fun with GUGA🤘
